The graph of y=cos ⁡x is transformed to y=a cos⁡(x−c)+d by a vertical expansion by a factor of 3, then translated π/2 units left and 2 units up. the new equation is:

y = 3 cos (x + π/2) + 2

y = 1/3 cos (x - π/2) + 2

y = 3 cos (x - π/2) - 2

y = 3 cos (x - π/2) + 2

y = 3 cos (x + π/2) + 2

Step-by-step explanation:

The transformed equation of y = Cos x  is  y=a cos⁡(x−c)+d

Where

Keeping these points in mind, the correct equation should have a = 3, c = + π/2, and d = +2

So we can write:

y = 3 cos (x + π/2) + 2

first answer choice is right.

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
